Thats an easy one to debunk. First of all, as the video already said so, there is a chance all six dices will show six by sheer coincidence alone. In other words, your proof is pure by chance, nothing to do with God. Secondly, you have in the video a wild assumption that God must listen and fulfill your prayer for all 6 dices to show 6. In other words, rather than proving that God does not exists, it just showed you are either very silly or dishonest and unscientific, or both sir. So do you have any definite proofs that God does not exists
